The effect of a particle size distribution on the coercovity and remanence of a fine particle system
Abstract
Experimental measurements of the coercivity and remanence of a fine particle system have been interpreted as arising from a lognormal particle size distribution. Good agreement is obtained between theory and experiment with KVp/ kT a constant ≈13, where K is the anisotropy constant, and Vp the critical volume for superparamagnetic behaviour.
